SU95170A1 - Vibration tamper for compacting concrete and other materials - Google Patents

Description

The subject of the invention is vibrating and tamping, intended for compacting concrete, asphalt concrete and soils.

The known vibration devices of this kind, based on the creation of vibration oscillations caused by alternating action of the shock of the youngsters and the strength from the balancers of the vibrators, have the disadvantage that the vibration vibrations affect only the surface layer of the material being compacted.

In the proposed invention, this disadvantage is satisfied by the fact that instead of simple harmonic oscillations that are used for this purpose, resonant oscillations are used, created by two eiphino vibrators that cause resonant vibrations of the spring-loaded vibrating mass, which strikes the optical ground.

In addition, the vibrating mass face of the tamper has a sabzhen oblique protrusion, along which the peak support slides, is fixed

on upnaya site. This is done to simultaneously move the pad in a horizontal plane along the surface of the material being compacted.

Shock pulses accelerate the rammer compaction process.

mateoolrial and rayrostran otst depth, which determines the improved productivity of the rammer.

 schematic

The drawing shows the abundance of the front vibratory tamping.

On sealing

site /

the rammers have two directional bolts 2, on which are fixed the springs 3. Between these springs there is a vibrating mass 4,

On the vibrating mass, there are two electric motors 5 with an unbalance, making the same number of revolutions and the same power and kinetic moments from the debalais. The electric motors rotate in different directions, with the result that the vibrating mass improves vertical-directional resonant oscillations. The vibrating mass, the spring stiffness and the number of revolutions of the unbalances are adjusted in such a way that two strokes of the unbalances accounted for one blow to the sealing pad.

AT . The middle part of the lower surface of the vibrating mass is fixed by the firing pin 6, under which l is located the Jacob-hale 7, fastened to the upper surface of the seal, 1, to her platform. On the striker, a lateral protrusion is made, on which the slide is a slide stop 8 fixed to the compaction of the platform.

In the process of tamping operation, when after the impact the vibrating mass moves upwards, the beveled protrusion on the striker afterwards, acting on the roller stop, will force the dense plane to move in the horizontal plane to the right. At the moment of striking the striker on the anvil, the compaction seal will move in the opposite direction.

Thus, during one oscillation of the vibrating mass, the compacting platform of the tamper, in addition to the vertical movement, will make two horizontal movements: the first in its form removes it from the surface of the sealing material and the second at the moment of impact of the striker on the arch.
